摘要： An antenna coupling enables communication across a barrier to radio frequencies. The antenna coupling comprises first and second antennas. The first antenna is adapted for positioning on a first side of the barrier, and is capable of receiving from and transmitting to a first transceiver disposed on the first side. The second antenna is adapted for positioning on a second side of the barrier, and is capable of receiving from and transmitting to a second transceiver on the second side. The interconnection of the first and second antennas through the barrier comprises the antenna coupling. The antenna coupling enables the first and second transceivers to communicate across the barrier over the desired range(s) of radio frequencies. In a related aspect, the antenna coupling may also include a filter interconnected between the first and second antennas to prevent radio frequencies outside of the desired range(s) from being transmitted across the barrier.

摘要： A quadrature coil with a unique arrangement of vertical and horizonal mode coils allows for superior magnetic resonance imaging and spectroscopy through higher sensitivity and more uniform imaging over the region from the head to the crest of the aortic arch. The coil has vertical-mode conductors at approximately 30.degree., 150.degree., 210.degree.and 330.degree.with respect to a longitudinal axis, and horizontal-mode conductors at 90.degree.and 270.degree.. The horizontal-mode conductors are connected at the far end of the coil at an electrical midpoint of the horizontal-mode conductors, such that a voltage null will exist there when the coil is operated in vertical mode. The vertical and horizontal mode feedpoints are located at a head end of the coil, which is hinged into halves to permit easy access by and to a patient.

摘要： A head coil for use with a parallel-imaging compatible MR system is disclosed, as is a method of making, and a neurovascular array (NVA) equipped with, same. The head coil includes conductive rings and rods configured to produce a plurality of electrically-adjacent primary resonant substructures about a birdcage-like structure, with each such primary resonant substructure including two rods neighboring each other and the short segment of each of the first and second rings interconnecting them. The primary resonant substructures are isolated from each other via a preamplifier decoupling scheme and an offset tuning scheme thereby enabling each primary resonant substructure (i) to receive an MR signal from tissue within its field of view and (ii) to be operatively couplable to one processing channel of the MR system for conveyance of the MR signal received thereby (iii) while being simultaneously decoupled from the other primary resonant substructures.

摘要： A local or surface coil including a decoupling circuit to allow the coil to operate as a receive-only coil in a host MRI system, in which case the system body coil typically provides the transmit signal. Further, the local or surface coil includes a circuit to defeat the decoupling circuitry for both low power [receive] and high power [transmit] functions to allow the same physical coil to be used as a transmit/receive coil in addition to a receive-only coil. The two modes of the coil allow the user to select the mode of local or surface coil operation best suited to the particular type of imaging being performed.

摘要： A device for injection of a fluid into a patient includes a container adapted to hold the fluid and defining an outlet through which the fluid can exit the container. A pressurizing mechanism is in connection with the container for pressurizing the fluid, and an actuator is in fluid connection with the outlet. The actuator has a first state in which fluid is prevented from flowing through the outlet and a second state in which fluid can flow through the outlet. The injection device further includes a flow regulator to control the flow rate of fluid in fluid connection with the outlet. The container, the pressurizing mechanism, the actuator and the flow regulator can be MR compatible, thereby making the device suitable for use in or near the bore of an MR scanner.

摘要： An intracavity probe for use with an MR system allows images and spectra of internal anatomical structures to be obtained. The intracavity probe houses within its balloon-type enclosure a single-element quadrature coil sensitive to both the vertical and horizontal components of the MR signal. The quadrature coil by means of its output line is designed to plug into a dedicated interface device with which to interface the quadrature coil with the MR system. Drive capacitors within the coil in conjunction with the electrical length of the output line and phase shifting networks within the interface device enable complete decoupling of the quadrature coil from the transmit fields generated by the MR system. Preamplifier, power splitting and combining networks within the interface device process voltage signals representative of the horizontal and vertical components of the MR signal and enable them to be conveyed to the input port(s) of the MR system.
